The Philadelphia hospital accepted the computer-based list of worrisome fevers, but then deployed their best doctors and nurses to apply Grimaud’s “highly practiced touch” and look over the children before declaring the infection was deadly and bringing them into the hospital for intravenous medications. Their teams were able to weed out the algorithm’s false alarms with high accuracy, and in addition find cases the computer missed, bringing their detection rate of deadly infections from 86.2 percent by the algorithm alone, to 99.4 percent by the algorithm in combination with human perception.
